Vithin the hub of the belt-wheel D2 is a nut D3, which works on the screw D', thereby reciprocating the shaft D and withdrawing the sack-holder when the shaft E is rotating in one direction and advancing it when it is rotating in the opposite direction.

F F are two half-shells which lie in the position shown in the dotted lines in Fig. 4 when the sack-holder and frame are withdrawn and which are pivoted at F F to the standards F2, secured to the main frame A. As the sackholder frame is advanced the cam-bars G G, one upon each side of said frame and formed, as shown, so as to present their cam-faces to the halfshells, will lift these half shells gradually upward until the sack holder reaches its farthest forward position, when the two half-shells F F will be firmly pressed upon the sack, forming astrong shell about it to strengthen it during the operation of baling.

H is a plate secured tothe end of the rod H', the other end of which is supported by the abutment H2. lVhen the sack-holder is moved forward, this disk H passes through the extended sack and forms a back plate to close the end of such sack during the operation of baling. Y

J is the hopper into which the fiber to be baled is thrown. J is an opening in said hopper communicating with the feed chamber or cylinder K. Y

L is a piston adapted to be reciprocated in the feed-chamber by the hollow sleeve M. This sleeve upon its outer surface has a screw which is operated by thernut M in the hub of the belt-wheel M2,which is driven from the shaft N. This shaft N' is provided with a device similar to that hereinbefore referred to in connection with shaft E', whereby its direction of rotation may be automatically and periodically reversed. The nut M when in operation will therefore be turned alternately in opposite directions and the sleeve M will be reciprocated. This sleeve M surrounds the piston-rod U between the piston L and hand-wheel U2 and by its'reciproca- The lever E7 in turn re- O2 is an arm projecting from the door O in y the path of the piston L and adapted to be caught by said piston as it is withdrawn from its forward stroke to open the door.

It may be desirable to strengthen the bale by bands o f hoop-iron or other material. this event the bands already formed may be slipped over the sack after it has been placed upon the sack-holder and before it has been InY tightened. In order to have these bands prop-n erly spaced and to still further strengthen the sack and bale during the operation of filling and of removing the holder, use may be made of the device illustrated in Figs. 7, 8, 9, 10, and l1, which may be termed a spaccia Figs. 7 .and S are cross-sections through a por- Y tion of the holder, sack, spacer, and outer shell as they are during the operation of filling. spacer, and outer shell as it would appear viewed in the direction of arrow in Fig.V S,

with sack and holder removed. Figs. 10 andVv ll are longitudinal sections through the parts as they would appear along line lO 10 and 11 ll of Fig. 9. The spacer consists of two straps or bars of metal R, one of which is seen in Fig. 9, to which are attached the ends of the half-hoops R. This device consists of a cylindrical half-shell to conform to the shape of the bale and is formed of two bars placedV longitudinally one upon each side of the half- A shell and a number of half-hoops, each of Y which is attached at each end to one of theV bars.

the sack when the spacer is placed in position.

F3 is a .inger or projection on the outer shell F', so positioned that when the half-shells are closed upon `the sack this finger will engage the end of the bar R to brace it and hold spacer, hoops, and sack in place upon the bale while the holder is being withdrawn.

The operation of my invention will by this time be clear. The frame carrying the sackholder being withdrawn and the sack-holder being slightly collapsed the endlessV sack will be slipped intoposition over the sack-holder. The hoops will now be slipped over the sack and placed approximately in their proper p0- sitions. The spacer will now be thrown'upon the sack, and the hoops Rs will be so adjusted that they rest within the slots R2. The handwheel C3 will now be operatedto elevate the half-shell C' and stretch the sack taut. The lever F.T will then be thrown down into the position shown in Fig. 6, and the sack-holder and frame will be advanced up to the posif tion shown in Fig. l, `when the lever E7 will be lifted again to bring such motion to a stop. As the sack-holder moves forward the cambars G lift the sections of the outershell F until they rmly clasp the sack-holder and sack. The lever N7 will then be thrown down into the position shown in Fig. 5, whereupon the piston L will reciprocate in the feedingchamber K. The hopper being suppliedV with the fiber to be balcd this will pass when the Ico The bars R have the cross-slots B,L Y properly placed to receive the hoops R3 upon Y parts are in the position shown in Fig. l into the feeding-chamber. As the piston L moves forward the material in the feeding-chamber will be forced into the sack. The action of the spring O will close the door O of the aperture J as the piston is advanced, and as the piston is withdrawn it will strike the arm O2 and open' said door, so as to permit a fresh supply of material to fall from the hopper into the feeding-chamber. This operation willccntinue until the sach has been rammed full of the material and the same is compressed so far as the ordinary strokes of the piston will compress it. It may be desired to apply still greater force to still further compress the bale, and this may be done by the use of the hydraulic jack. To apply this jack, the lever N7 will be thrown up when the piston has been thrust forward by the sleeve lll and is pressing against the bale. The handwheel U2 on the threaded portion U of the piston-rod U will then be turned back toward the end of the piston-rod. The hydraulic jack Tis mounted in a frame hinged at each side to the main frame A, and during the ordinary operation of the machine will be swung down out of the way of the reciprocating piston-rod. It will now be swung up into the position shown in the drawings by moving the lever T3, which turns the shaft-carrying cam T4, and immediately upon the frictionwheels T2 upon the shaft which drives the pumping-pistons of the hydraulic jack coming into engagement with the friction-wheels T' upon the rotating shaft N the jack will be thrown into operation and its presser-piston will force the piston-rod U and piston L forward, thereby compressing the bale. The plate H at the other end of the bale, which is backed by the rod H and abutment H2, will receive the strain when the hydraulic jack is applied. lVhen the bale is sufiiciently compressed, the lever E7 will be thrown down, and the frame carrying the sack-holder will be withdrawn. The plate H, backed by the rod H and abutment ll2, will hold the bale and prevent its being withdrawn with the holder, and the lock F3, bearing against the end of the bar R, will securely hold the spacer and the bands in their proper positions. As the holder is still further withdrawn the cambars G will permit the half-shells F to fall back into the position shown in dotted lines 'in Fig. 4, and the finished bale will lie in one or the other of these half-shells.

In designing the baliug-press herein shown I have had particularly in mind the equipment of a complete plant for scouring, drying, and baling wool on a large scale, of which the baling-press herein shown and the scouringmachine shown in my application pending cotemporaneously herewith are to form features; but I am well aware of the different uses to which my invention herein set forth may be put and of many Variations and modiications which may be made in someof the parts thereof in order to adapt it to different uses, and I do not wish to limit myself to the precise construction of parts here shown by reason of the language I have used in describing my invention having been employed with reference to one concrete embodiment thereof which I had in mind. For example, I have referred to the cylindrical shell C C' throughout as a sack-holder; but it might be desirable in the baling of certain substances, such as hay, not to employ any sack, and it will readily be seen that such bales could be formed with a press substantially as herein shown, the hoop-iron bands being sufficient of themselves to hold the bale in shape when it is formed.

What I claim as new, and desire to secure by Letters Patent, is-

In a baling-press a sack-holder adapted to receive the sack in which the bale is to be formed and to hold the same while the bale is being formed therein, said sack-holder consisting of sections movable with reference to each other so that the sack-holder may be partially collapsed to facilitate placing the sack thereon.
